Maybe some as this?:

# get (unique) package list (from 'yum list installed' output):
yum list installed|awk '(NF == 3){print gensub(/\.[^.]*$/,"",1,$1)}'|sort|uniq >old-rpm-list

# get list of RPMs on minimal F18 installation:
rpm -qa --queryformat '%{NAME}\n'|sort|uniq >new-rpm-list

# install RPMs which was only on old Fedora distro:
comm -2 -3 old-rpm-list new-rpm-list|xargs -r yum install

PS: You perhaps can omit to excluding already installed packages, yum
should solve this.
